ABSTRACT
The plants of Chloranthaceae are widely distributed and rich in resources in our country, records of ancient herbs indicaded that various species of plants of Chloranthaceae can be used for medicinal purposes, especially the Sarcandra glabra which with the least toxicity and possessed the function of clearing heat and cooling blood, activating blood to eliminate spots and removing wind and dredging collaterals. Based on the theory of herbage and by the method of consulting the past herbal literature, we summarized and analyzed the medicinal history, distribution characteristics of herbage geography, characteristics of herbage ecology, standard collection situation and the modern toxicology research of Chloranthaceae plants. Therefore we explained the scientificity for selection of medicinal herbs of Chloranthaceae plants, and provided a theoretical and scientific basis for further research of Chloranthaceae plants.
ABSTRACT
Collecting different commodity grade Gardenia jasminoides of wild and cultivated varieties all over the country, obtaining color information from each batch of G. jasminoides by the standard D65 light source and image acquisition system, quantifing the gardenia plumpness information by the digital display vernier caliper, determinating 6 kinds of effective components of G. jasminoides by HPLC, classifing from ten indicators by two step clustering analysis and correspondence analysis method of statistics, clearing the importance of the traditional identification indexes, establishing multiple corresponding relation between the skin color and commercial specification of G. jasminoides,exploring the correlation of the skin color and chemical composition, to provide the reference for the reasonable division of commercial specifications and grades of G. jasminoides. Medicine is divided into two classes and has obvious distinguish meaning, The importance of the skin color is greater than the plumpness in traditional identification characteristics, it can accurately distinguish the specifications of G. jasminoides. We improve and rebuild the standard of commodity specifications and grades of Gardenia jasminoides Ellis and establish the rapid evaluation method by the study, it provide a new way and idea for the comprehensive evaluation of G. jasminoides quality.
ABSTRACT
The application of ArcGIS and Maxent modelto analyze the ecological suitability of Gardenia jasminoides.Taking 85 batches of Gardenia as the basis of analysis, the selection of ecological factors for the growth of Gardenia. The results showed that the average precipitation in April, the average precipitation in November and the average precipitation in August were the most important factors affecting the growth of Gardenia. The relative concentration of Gardenia suitable growth region,north to the south of Shaanxi province, south of Henan, central Anhui, south to the north of Hainan province, west to central Sichuan province, east of Zhejiang coastal area, northeast of Taiwan.
